Hi,
It is actually a bug which makes ActivePresenter 3.0.1 crashes when saving profile if there is no enabled audio recording device.
To record audio from system (in Windows 7), please select Stereo Mix (or Rec. Playback,..) as input device. If it is not shown in list, please try following steps:
- Right click on Audio icon on the Taskbar
- Select Recording devices from menu
- A Sound dialog will appear, in Recording tab, right click and select Show Disabled Devices from menu.
- Find the Stereo Mix item, right click on and select Enable.
If Stereo Mix is found and enabled, restart ActivePresenter and choose it as input device. I think you can capture audio from system now.
Hope this help!
